On February 19, 2026, the Sagano Scenic Railway (Ukyo Ward, Kyoto City) announced that 18 bridges and tunnels passed by the Sagano Torokko Train, including the 85-meter-long Hozugawa Bridge (Ukyo Ward, Kyoto City), have been registered as national tangible cultural properties. A commemorative train will run this spring.

Nine tunnels and nine bridges along the railway line were registered on February 10, in recognition of their historical value and the landscape that supported Japan's modernization.

Many of the tunnels largely retain their original appearance from when they were built in 1899, and the bridges retain their maintenance ingenuity, such as welding reinforcement from the Showa era, to extend their service life.

The Sagano Scenic Railway will resume trolley train service on March 1, after a winter suspension. To commemorate the cultural property registration, a commemorative train introducing the 18 facilities will run from April to June. A commemorative symposium is planned for May.
